spiral wound gasket

The Function of spiral wound gasket 1.With better compressibility and recovery; 2.With plastic property, it can adapt to the sealing surface with concave and convex to fill the gap of sealing surface and ensure to keep the better sealing performance under the environment with fluctuation temperature and pressure. 3.With better mechanical property of tensile strength and stretch rate. 4.With excellent performance of corrosion resistance, it cant break in some extreme medium; it wont generate large expansion and shrink. 5.It wont be softening under the condition with high temperature; it wont be harden shrink under the condition with low temperature. 6.With the advantage of enough strength, it wont be broken under the condition with heavy load; it wont be blown out under the condition with high pressure.

Four types of different structure TSA Style Basic construction type It consists of metal strip and filling materials, Suitable for tongue and groove, male and female or flat face and recess flanges TSB Style With inner ring type It fitted with the metal inner ring on the basis of basic construction type to become the block of pressure; meanwhile, it fills the blank of side of flange and the gap of inside sealing side. This design can protect accumulate the solid, reduce the impact of liquid, minimize the erosion of sealing surface. They are suitable for using on male and female flanges. TSC Style With outer ring type It fitted the outer ring, which enables the gaskets in the middle of flange, to provide additional resistance to prevent gaskets burst. TSD Style With inner and outer ring type It fitted with inner ring on the basis of with outer ring type as the internal compression point, at the same time, it becomes resistance of heat and corrosion to protect the sealing surface of gaskets and prevent the flange from corrosion. This type of gasket is applied to flat and raised face flange; especially suitable for use under the condition with high temperature.
